Material Notes:
POLITEF (PTFE) was invented in 1938. It is the most preferable and known fluoropolymer among fluorine polymers. It has superior properties that none of the other industrial plastics have because of its strong connection between the carbon and fluor atoms and its molecular structure made of a long and linear carbon chain, which is full with fluor atoms.It has the widest working heat interval among all the industrial plastics (-260°C and +260°C) , complete unlimited resistance against humidity, against environment conditions and against all the chemical materials used in industry. It has the lowest static and dynamic friction coefficient among all the known solids, superior electrical isolation, non-adhesiveness, non inflammability and other properties like these. In addition to these, it has sufficient mechanical properties and full resistance against all chemical materials. All these provide POLITEF to be preferred more than the other materials at many usage areas. Moreover many times only POLITEF is being used.POLITEF, is a material which can be used at many fields because of its above mentioned properties. Medicine, air and space technologies, cable and cable structure groups at computer sector, filter products, systems for determining leakage, valve spare parts, mechanical spare parts, electrical industry, food industry and textile industry are only small examples of POLITEF`s usage areas.
